Joomla 2.5 how to detect failed front-end log-in attempt

I am developing a Joomla 2.5 system plug-in that needs to perform certain tasks when a front-end visitor has attempted a log-in but failed.

How can I detect in my system plug-in that a user authentication has failed?

Solution

  • There is an event onUserLoginFailure that you can catch.

    onUserLoginFailure

    Description: This event is triggered whenever a user authentication request is failed by any plugin.

    Parameters: Two parameters. The credentials array for the user (see onAuthenticate), and the JAuthenticateResponse that caused the failure.

    Return Value: Unknown. The return value appears to be ignored in any case.

    Used in files: libraries/joomla/application/user/authentication.php

    Reference: onUserLoginFailure
